Overview

The VH839 is an eight-port video balun hubs with built-in surge suppression. Systems operate with other Nitek UTP video equipment including, video balun hubs, standard video balun transceivers or active receivers.

The VH839 video balun hubs are multi-channel video transmission devices that provide a low cost means of sending quality live video over Category UTP cabling. The systems can also adapt to existing communication and computer network spare pairs, or new cable installations. The VH839 can send video up to 750 feet (225 meters) when used with other products in the VB37 or VB39 family. When used with model TR515 or TR560 active receivers, distances of 1,500 feet (450 meters) and 3,000 feet, (900 meters), respectively, can be attained. The VH839 is designed to provide superior immunity from noise and interference, such as RFI and EMI.
